INJORA Silicone Rubber Tire Inserts 4-Pack Green for 68-72mm x 24-27mm 1.3" RC Tires

These INJORA silicone rubber inserts are designed for RC tires with an outer diameter of 68–72 mm and a width of 24–27 mm. They come as a set of four green inserts intended to replace standard foam, providing firmer sidewall support that helps tires hold their shape during crawling. These inserts are compatibly with several specific INJORA tire models, though fitment with other brands may vary due to differences in tire wall thickness.

What tires do these inserts work with?

The inserts fit tires sized 68–72 mm outer diameter and 24–27 mm width. INJORA has validated compatibility with the following tire models: 70×27 mm Swamp Claw (T1319), 70×26 mm Cling On (T1320), 72×24 mm XHX Pin (T1321), 70×26 mm Crawler Tire (T1311), 70×27 mm King Trekker (T1314), and 68×24 mm Gripmax (T1350). For tires from other manufacturers, measure your tire's inner wall thickness and compare to these inserts before buying, since wall thickness differences can affect fit.

Key specs at a glance

How do they compare to foam inserts?

Silicone rubber inserts offer more consistent sidewall support than typical foam. Foam can compress unevenly over time, especially after getting wet or dirty. These silicone inserts are waterproof and temperature resistant, so they maintain their shape and support in wet or muddy conditions. The firmer structure helps prevent tire folding during turns or when crawling over obstacles.

Installation notes

Insert the silicone rubber piece into your compatible tire before mounting on the wheel. Ensure the insert sits evenly inside the tire cavity. Because tire wall thickness varies by brand, you may need to test fitment carefully. If the insert seems loose or too tight, it may not perform as intended.

Common questions

Will these fit my non-INJORA tires?

INJORA states that compatibility with non-INJORA tires is not guaranteed due to differences in tire wall thickness. Measure your tire's inner dimensions (68–72 mm diameter, 24–27 mm width) and compare to the insert size. If your tire wall thickness is similar to INJORA tires, they may work.

Can I reuse these inserts if I change tires?

Yes, these inserts are durable and can be moved to other compatible tires as long as they remain in good condition. They are reusable.

Are these inserts waterproof?

Yes, the silicone rubber material is waterproof and also temperature resistant, making them suitable for all-weather RC crawling.

Do they come in a pair or a set of four?

This listing includes four individual inserts, enough for four tires (one full set for most 4×4 RC crawlers).
